(also) Stuck on “Loading Palette” Screen

TL;DR - same behavior as here, on latest version.

Hi,
I've been using node-red for several months, yet decided to have a fresh install.
After removing everything (node-red, node.js, npm), I've installed the latest nvm-windows, node.js (LTS), and node-red. Upon startup, I'm greeted with this:

startup log:

Can you check the browser console for any errors?

If there is an error that mentions e.trim then you've hit the issue reported here: [problem] Not work flow editor Node-RED 1.3.4 on Chrome

Well have it fixed in the next release, but the workaround for now is to try a different browser.

ItayKishon-Vayyar · 11 May 2021 13:00

There is an error, yet unrelated to e.trim (shown below).
Edge (v90) shows the same behavior, with the same console error (probably being based on Chromium?)
Firefox (v88) experiences the same loading freeze, yet with a slightly different error message (seems to be from the same origin, though).

Seeing as the browser being used isn't the issue, is there a previous node-red version I should use?
Thanks.

Colin · 13 May 2021 08:32

You can roll back to a previous version by running, for example
npm install -g --unsafe-perm node-red@1.3.3

Then restart node-red.

If you find that it is fixed by a particular version then let us know.

@knolleary is the purify map warning normal on windows, or could there be a relationship between the warning and this issue?

knolleary · 13 May 2021 08:33

is the purify map warning normal on windows, or could there be a relationship between the warning and this issue?

That is unrelated to the issue here.

@ItayKishon-Vayyar have you got any custom nodes installed? This error can happen if there's a "bad" node installed. I'm working on some better handling of these cases for the 1.3.5 release.

ItayKishon-Vayyar · 13 May 2021 08:36

This is a completely fresh install, after removing all node-red,node.js & npm.
I've installed the the latest nvm-windows, node.js (LTS) - v14.16.1, and node-red - v1.3.4.
I'm trying the previous version (1.3.3). Will update.

knolleary · 13 May 2021 08:41

Can you follow these steps to get some more information:

open the chrome developer tools and switch to the Network tab
Click the button to clear the log
Reload the page
type 'nodes' into the filter box.
You should see an entry like nodes?_=123456 (the number will be different).
Click on that entry and then the 'Response' tab.
Copy the contents and share it with us.

(wow, thanks for the quick & detailed response.)

Hmmm - browsing through that response, I see a node which I've previously tried to install (which caused me some problems, leading to the supposedly fresh install). Namely: node-red-contrib-amqp.
That means that removing all the above hasn't completely cleared all the settings from the computer.
I'll try to find & remove all those old settings.

Hi @ItayKishon-Vayyar

yes - node-red-contrib-amqp is the cause of the issue.

If you have a look in the file .config.nodes.json in your node-red settings directory you should find a reference to that node including the full path to where it is being loaded from.

Colin · 13 May 2021 08:53

Did you delete or rename your .node-red folder for a 'completely fresh install'. Otherwise you will not have removed the problem node.

ItayKishon-Vayyar · 13 May 2021 09:00

Apparently...

So although I found the node-red-contrib-amqp reference in the .config.nodes.jsonfile:

    "node-red-contrib-amqp": {
        "name": "node-red-contrib-amqp",
        "version": "1.0.2",
        "local": true,
        "user": true,
        "nodes": {
            "amqp": {
                "name": "amqp",
                "local": true,
                "user": false,
                "module": "node-red-contrib-amqp",
                "file": "\\Users\\ItayKishon\\.node-red\\node_modules\\node-red-contrib-amqp\\lib\\amqp.js"
            }
        }
    }

, the folder itself doesn't exist.

Removing the above reference from .config.nodes.json solved the issue, and the system has loaded. And may I add - with all my previous flows, as this was obviously not a completely fresh install...

Now everything is working again. I wonder - has the invalid node reference caused the loading problem?

knolleary · 13 May 2021 09:19

That is interesting to know - and gives me an idea as to how you got into this state. Will see if we can avoid it in the future.

knolleary · 13 May 2021 14:51

The handling for this scenario is now fixed in git for 1.3.5.

ItayKishon-Vayyar · 13 May 2021 14:53

Thanks so much.
